MVC Razor View The name ‘model’ does not exist in the current context

Error: 

you have added new area and added controller models and view and when you run your project you face the error :The name ‘model’ does not exist in the current context

Reason :  I hope you have deleted default files added by Visual studio , specially focusing on web.config file .

Now add new web.config file  and copy the below code

Hope it works for you .

ASP.NET MVC partial view works fine in local but does not render when published

When new MVC project is created with some partial views.

The projects works fine when it is build in local but when published to server it shows message as :

The partial view '..' was not found or no view engine supports the searched locations. The following locations were searched:
~/......

If your created views are in another project or another folder from your current project this is the issue , Basically the files should be  in the web site project, in it's views folder,  and  most important is

 the build action should be set to Content and not to copy to the output folder.

Hope it helps.

Initialize class as array and assign values to its elements using C#

Suppose you have ClassA with three members. When you try to initialize class as  

ClassA[] varrayData = new ClassA[Length];

at this point your class initializes not class members.When you try to access the class members it throws null exception.    So solve the issue, find the simple way of initialize class as array with its members

 public class ClassA
    {
        public string Name { get; set; }
        public double Address { get; set; }
        public string Notes { get; set; }
    }

    public void YourMethod()
    {
        ClassA[] varrayData = InitializeArray<ClassA>(Length);
        for (var j = 0; j < Length; j++)
        {
            varrayData[j].Name = "testname" + j;
            varrayData[j].Address = ""
            testAddress + j;
            varrayData[j].Notes = "testNotes" + j;
        }
    } 

    //use this piece of code that does the magic:
    private T[] InitializeArray<T>(int length) where T : new()
    {
        T[] array = new T[length];
        for (int i = 0; i < length; ++i)
        {
            array[i] = new T();
        }
        return array;
    }

Invalid URL value. A URL field contains invalid data. Please check the value and try again

The URL that you are creating doesn’t exceed 255 characters. This is because the Hyperlink type column in SharePoint does not accept more than 255 characters as an URL. This is what had happened personally to me . Had a pretty tough time figuring it out myself.

Check that your URL is well-formed. To check this, try to browse the URL, that you are generating, in IE and see whether it points to your desired target. Just Copy paste the URL generated to the Address bar of IE and press enter. Ideally this should open the page you are trying to link to. If it is not then you instantly know that what you are generating is wrong. Correct it!

You may get the URL generated runtime from inside your Code by logging it into the Event Log or just by redirecting it to a text file or invoking IE by passing the URL generated as a parameter.

If you are directly assigning the value to the column like:

Item[""] = “,”, then check that you are not missing the after the comma.

The best possible way to do it I feel is in this way:

SPFieldUrlValue yourURL = new SPFieldUrlValue();

yourURL.Url = "";     // For example: www.microsoft.com.

yourURL.Url = yourURL.Url.Replace(" ", "%20");    // This is however optional.

yourURL.Description = ""; // eg:Microsoft.

HTTP Error 500.0 - Internal Server Error Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll" failed

HTTP Error 500.0 - Internal Server Error

Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll" failed

Problem :

If you install .Net framework in machine that already contains .Net Framework 4 , it caused the error

Solution :

Get a command prompt in administrator mode and go to 
C:\Windows\Microsoft .NET\FrameWork64\v4.xxx(version number )
and run 
aspnet_regiis -r. 


It will re-register the right libraries.

For any other kinds of framework locate the exact folder location of framework 4 , fine the file name asnet_regiis and run the command as above .

Now it solves the issue  hope if will work for you.
